I have looked all over the site and I cannot find anything definitive ,or should I say "informative", on what hardness is best for what guns. I have read Fryxells book and it is all revolvers. I have read all through the facts section and just about everything I can find that even comes close to bullet hardness in the Cast Boolit section. Nothing really addresses guns like the 45 acp or 9mm. The 30-06 or .223 are also not represented. Those are just the ones I am looking for so I am sure there are plenty more. I have seen some individual references of what some people have used but nothing as a general guide. Such as a 45 acp is best when used with BHN of xx. I am not looking for all of the thousands of recipes for mixing the alloy, that is what the alloy chart is for. I am just looking for a general figure to tell me what is a good number to look for. It may be on here but my search in the search box went nowhere, I have never had any luck searching forums, including my own forum.
